There isnt one, not one, instance where its known what pattern of neural connectivity realizes a certain cognitive content, inate or learned, in either the infants nervous system or the adults. To be sure, our brains must somehow register the contents of our mental states. The trouble is: Nobody knows howby what neurological meansthey do so. Nobody can look at the patterns of connectivity (or of anything else) in a brain and figure out whether it belongs to somebody who knows algebra, or who speaks English, or who believes that Washington was the Father of his country.

In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.
